IMPROVEMENT IN VVENTILATORS FOR HATS.

'l Specication forming part of Letters Patent No. 174,998, dated March 21, 1876; application tiled January 22, 1R76.

Be it known that L GHARLEs F. ABBOTT, oi' the city, county, and State of New York, have invented an Improvement inVe-ntilators for Hats, of which the following is a specilication:

This invention relates to that class of ventilators for hats in which a piece of corrugated leather or like material is interposed between the sweat-band and the body-of the hat at the front of'the latter, in such manner as to provide passages through which, when the hat is worn, air can pass up in contact with the forehead of the wearer to the interior of the.hat,.thereby not only cooling the head, but also, by the contact of the upward current of air, the forehead' of the wearer aforesaid-it being usual to provide a hole or orice in the crown of the hat, to permit the es' cape of heated air and insure the continuity of the current so long as the hat remains upon the head. A

As such ventilators have been hitherto made, the corrugations-have been kept intact byn means of strips of clot-h pasted or cemented upon one side of the corrugated' leather, to prevent the spreading or elongation of the same. This construction of the corrugated Ventilating-piece is expensive and unreliable, requiring comparatively high priced' and skilled labor in its manufacture, and the strips detached. 4

Thepurposeof my invention is to obviate these drawbacks by providing a VVentilatingpiece which may be quickly and strongly made by extremely cheap and almost Wholly unskilled labor, andfwhich, moreover, 'from the durability arising from its peculiar construction, .will be as durable asy the hat to which it may be applied. -v

To this end my said invention comprises a" flexible corrugated ventilatingpiece, having one or more wires passedftransversely through its corrugations and made fast ateach end, in such manner as to securely hold the corrugations against all vtendency to flatten or spread out, the said wirey or wires being, from the mode of attachment, not liable to displacement or deran gement froln any vicissitude of use. i l

being extremely lia-ble to stretch or vbecome Figure 1 is a central verticalsectional view ot' a hat fitted with a Ventilating-'piece made according to my invention. Fig. 2.`is a horizontal sectional view ofthe same.L Fig. 3 is a side view, representing the corrugated ventilating-piece made according to my invention, as aforesaid, detached; and Fig. 4 is an edge view of the same on a larger scale.

A is the hat, provided, in the usual tmanner, with an orifice, a, in the crown. B is the sweat-band, disposed in the usual place ad: jacent to the brim. C is the corrugated ventilating-piece, which, when applied to use, is interposed between the lower part of the front ofthe hat and the adjacent front portion of the sweat-band, as shown in Figs. 1 and 2. The corrugations Ot' the Ventilating-piece C form passages a', through which air may pass up at the front of the hat into its interior, and thence`out through the orifice a, when the hat is Worn. [n the fabrication of the piece C the leather or like material is cut to proper size and contour, and is then crimped or corrugated by being passed between grooved rollers, or by other suitable means, the corrugations being transverse to the length of the piece. -When thus corrugated it is necessary to provide against the flattening lof the corrugations by the longitudinal stretching or elongation of the piece, as such flattening would close the passages a and destroy the utility of the device. In the means'adopted to prevent this lies the gist of my invention.

When the Ventilating-piece G has been corrugated,'as just hereinbefore set forth, I perforate the same from end to end through its corrugations, the perforations being,of course,

in line with each other and transverse to the corrugations. Through this line f perforations YI pass a wire, c, and, afterfaste'ning 011eend of said Wire to one of the endsb' otthe piece G, I draw the wire snugly "enough to cause the requisite bulge or prominence of the corrugations, and then fasten the remaining end of the wire to the opposite end ofthe piece C. The fastening ofthe ends of the wire, as aforesaid, may he doneby passing the same through the ends b ofthe piece C, and then folding, turning over,' or clamping the same by the use of pliers or other suitable implement.

piece is made, and the length of said wireis f rlnly sustained in the corrngations, it follows that thedetachment of the wire, and theloosening of the corrugations that would result therefrom, is eli'ectually guarded against, and inasmuch as the attachment of the Wire is a mat ter simple and easy for even an unskilled operative, the cost of manufacturing the ventilating-piece is very slight.

It will of course be understoodv that the Ventilating-piece C, as thus constructed. may v he secured in place in the hat by any suitable means, and' that the wire c has a diameter so p ing-piece.

small as to cause no appreciable obstruction to the:A passage of air througlilthe: passages a', provided by the corrugations in said ventilat The perforations in the corrugations aforesaid, for the reception of the wire or Wires, may be madeby any suitable means; but in practice I propose to use the implement shown and described in my application of even date; with thisI fory arpatent on improvements in apparatus for making corrugated ventilators for hats.

What I claim asmy invention is- The flexible corrugated Ventilating-piece C, having a wire 0r wires, c, passed through its corrugations and fastened 'at each end, substantially as and for the purpose set forth.
